“We wouldn't be even here if JAY didn't build that time machine!”

Cole to Jay

Season 15: Back in Time is preceded by Season 14 and succeeded by Season 16. Jay is the focus character. The main antagonists and villainous factions switched every episode. It is the sixth season and eighth installment of Emperor Garmadon's Series.

This takes place on Earth-101, a world where the darkness, Lord Garmadon speaks about in the finale of Hunted is not the Oni, it is past villains from the first 2 seasons of Ninjago Returning.

This season is not based on any real NINJAGO season, it is a completely custom story.


The ninja try to impress Master Wu but take it too far, when Jay invents a time machine and accidently sends the ninja to the past. How will they get back to the present?
